In Coimbra, Portugal, pollen seasons happen every year. There are four pollen seasons: tree, grass, weed, and olive.

Tree pollen season starts in January and ends in April. During this time, trees like birch, oak, and hazelnut release pollen. This pollen is carried by the wind and spreads everywhere.

Grass pollen season begins in May and lasts until July. Many types of grasses release pollen during this time. It's a bad time for people who react to grass pollen.

Weed and olive pollen seasons happen in the summer and fall. Weeds like nettle and sorrel release pollen, and olive trees do too. This pollen can cause trouble for people who react to it.
